Just in time for Halloween, the event brings together specialty bakers and pathologists from across the U.K. "It's two different worlds colliding but it's a very interesting mix," says Carla Connolly, the pathology museum's technician and a co-organizer.

Along side the bake sale, the museum is hosting a lecture series. Topics range from venereal diseases in 17th century London to the importance of dangers of cancer screening.

Through Sunday, the museum will display an assortment of cakes, chocolates, cookies, and cocktails that would add flavor to any haunted house. Some highlights include: a trio of cookies made to look like fungus-infected toes, red blood cell cupcakes, diseased kidney cakes, and a macaroon display that reads like a medical textbook diagram.
